LAMP or Moron vnH IoLEs] l Application filed November 20, 1926.. Serial No 149,613. I

The object of the invention is to obviate the dangerous practice of dimming when vehicles are approaching each other.

According to my inventlon, the lamp consists primarily in elongating a portion of 19 the lamp shell, the projecting portion of the lamp being on the drivers side of the car,

and the inner surfaceof the elongated portionof the said lamp shell ispreferably fitted with a reflector, an extension of the present reflector, or the said inner surface may be plated or coated with a suitable refleeting medium to increase the eiiiciency of the rays.

' Referring to the accompanying drawings; 0 Figure 1 is a general arrangement view showing the point on a car at which the lampis preferably mounted.

Figure 2 is aside elevation looking in the direction of the arrow head Z in Figure 1. 1

Figure 3 is a horizontal sectional view on line YY Figure 2.

Figure 4 is a detailed view showing the principle of mounting and means for ad'- justing the lamps. I g

The elongated lamp shell is indicated at '1. It will be observed that the projected part 1 is produced to provide a sufficient area of glass front as indicated at 2; the said projection is such that while the driver of the approaching vehicle is protected. against the dazzling rays, there are suflicient light rays directed to the road side to light up clearly any object of danger and permit and give the passing vehicle a wide berth.

The said means consistingyof a metal'band 7 lugs 7 attached thereto and a bolt 7 engaging the said lugs, all the parts providing means whereby the said band 7 A may be clamped upon the lamp shell 1. The said band 7 has a series of perforations? therein, and there is a pin 1 secured to the lamp shell 1, adapted to engage anyone of the said perforations in the band 7 'for the purpose of providing a variable adjustment for the lamp shell. i I I The supporting bracket is indicated at 7;

the driver to veer over on his side by law it consists ofbase 7 an upright member 7? and a resilient member 7 the metal band 7* is secured to the-said resilient member'at the outer end 7 H thereof,;and the said lamp shell '1 sits'on the entire length of the said resil- 1- themes ient member; the. top'surface of which is curved to correspond with the peripheral curve ofthe lamp shell 1. I r

The bracket 7 is preferably mounted on a side rail member of the chassis. Thebase :member 7 of the'sa-id bracket 7 has a hole 7 J therein, to engage with a pin 7 fastened ing upwards from the side rail member-of the chassis adapted to engage the curved slot 7 the said stud 7 is threaded to take a wing nut 7 which is provided for the purto and projecting upwardsfrom the said There is a stud 7 secured to andproject pose of securing the said bracket 7 in.its

desired adjusted position upon the chassis.

This adjustment in two directions is provided; the first mentioned adjustment is accomplished by slackening off the nutof the bolt 7 of the band 7 then turning the lamp shell 1 in the metal bands support; it

this adjustment would be in a direction concentric withthe axis of the lamp shell 1 to shorten the length of the projection of the rays from the lamp. The second mentioned adjustmentisprovided for the purpose of turning the .lamp shell 1 on'its'support horizontally round the pivot pin 7 K in this adjustment. the distance of the rays is not shortened, but increases the angle of projection to the line of travel.

The reflector 3' is indicated as being proj 1 duced in onepiece, and the other parts neces-.

' saryit'or a lamp as described consist ofa lamp socket, wiring and a bulb, indicated respectively' at 4 5. and 6; a bracket supporting the lamp in position is indicated at 7 I in Figure 1.

What I claim as new and desire to secure by Letters Patent is:

Improvements in and relating to the'lamps oi motor vehicles and the like. comprising an elongated lamp shell, a reflector lining i the inner's'urfaee of the elongated portion of the lamp shell, means foradjusting the axis thereof, and means for adjusting the i said lamp shell in a horizontal direction, the

said means for adjusting the said lamp shell consisting of a band clamped to the lamp shell, the said band having a series of perforations thereon, a pin attached tothe lamp shell adapted to engage With'any one of the series of the said perforations in said band,

a supporting bracket adapted to permit adjustment of the said lamp shell horizontally in an are upon a pivot, and means toclamp the said bracket in its adjustedposition, for the purpose described.

Intestinoony whereof I aflix my signature.
